Aluna
The Elder Brother’s Warning

In 1990, a BBC1 documentary film brought global attention to a remote South American people, the Kogi of Colombia, who were determined to caution us about environmental damage to the earth. Now, two decades later and convinced that their message has gone unheeded, the next generation of Kogi are reaching out to the world once more with a much more specific warning about the future of the planet.

There’s an excellent review about the film.
Go to the Aluna website to watch it. And below you find the film from 1990: From the Heart Of The World: The Elder Bothers’ Warning.
